In this part of the Tallinn University One-Minute Lecture series, Margit Kaldmäe, a doctoral student at the Institute of Mathematics and Natural Sciences, discusses everyday tools of laboratory work – cancer cells, the so called “immortal cells”, which stay viable several times longer than ordinary cells.

Scientists use these long-living cells for long-term and repeated experiments. The first cancer cells isolated from a human being were extracted from an endometrial tumour as early as 1951. The patient was Henrietta Lacks and the oldest and most frequently used cell line, “HeLa,” was named after her.
